of; this. character l wherein a ,continuou on; culatlon of chemlcally laden air-c 1s ma1n-' tained through a grain bin andlparticularly adapted for elimination of Weevil, brangbugjs, paras,1tes','{grainlice," l1arvae, and other 0011- ditions under which it isnecessary to treat grain. a a

A further object is to provide a chemical, tank in the pipeline, and through which air is forced by pump in its circulation. Also i to provide a suction pump onthe return line for speeding up the circulation when dea: sired, and means where either orboth of said pumps maybe operated.

means whereby the heated air with the moisy; ture taken up withinthe grain bin maybe 135, discharged to the atmosphere.

A further object is to provide'a heating element in the pipe line and through which the airmay be Icy-passed before entering the grain bin vfor relieving moisturefrom the air and discharging heated air into the-grain bin for drying purposes; Also to provide A further object is to provide a plurality of-discharge pipes extending upwardly into the grain bin, and terminating in hoods which will directthe air downwardly into thegrain body, and will prevent grain from passinginto thevdischargepipe. V

p A further object is to support upwardly extending discharge pipe or annular pipes cross connected whereby the air discharged intothegrain binwill be" distributed over I substantially the entire area of the bin. Also to provide valve means where lair entering end of the bin, and provided with downwardlyextending pipes, through which the binmay be discharged directly to the atmosphere.

:A further object is to provide annular dischargepipes cross connected to the upper leaving the "bin is forced and sucked.

therefore it will be seeir-that the rec'ireulat ing-airwill be heated as itcirculates. Under some conditions the use' of suctionpuiiip2 f-may not be necessary, for instance where there is a relatively small bulk ofigrain to be treated, and when it is desired to cut thesuctio'n pump 24out of the'circuit. This maybe accomplished by closing the' valves 25 and 32, and' of'coursethe valve :is then open as wellias valve 27, -but valve28 is closed and clutch 33 declutched;
